Filed: 2018-09-17
Abstract: The invention belongs to the field of organic chemistry, and particularly relates to a method for preparing a heterocyclic compound represented by formula I and salts thereof. Compared with the prior art, the invention avoids the use of cyanide, which is a highly toxic substance, and leaves no residual cyano group ion in reaction products and reaction waste, thereby greatly reducing the environmental burden. Moreover, the raw materials of the reaction in the invention have a low cost, a simple preparation method, a high yield, and are suitable for mass production. In addition, the inventors unexpectedly discovered that by using the method of Scheme 4, such as using a reducing agent and reacting under acidic conditions, the compound VIII can be reacted in one step and achieve deprotection, alkylation, and cyano group ion reduction simultaneously to obtain a target product. The disadvantages of the prior art that require multi-step reactions are thus greatly reduced.

IPC: B65D25/14
Filed: 2018-10-11
Abstract: A convenient barrel structure, comprising a barrel body. A weld ear for connecting a handle is welded onto an outer wall surface of the barrel body. A coated sheet is disposed on an inner wall surface of the barrel body corresponding to the position of the weld ear. The area of the coated sheet is greater than the welding area of the weld ear, and completely covers the welding position of the weld ear.
